  • IDENTIFYING WIDEBAND IMPULSE NOISE THROUGH A GROUP OF SMALL CHANNELS
    Publication number: 20150256420
    Abstract: Methods, systems, and computer readable media can be operable to determine impulse noise over a wide spectrum based upon measurements of impulse noise associated with each of a plurality of channels. Impulse noise can be observed on each of the plurality of channels and the observed impulse noise signals can be summed together. In summing observed impulse noise signals, a Fourier transform can be used to convert the observed impulse noises from a time domain representation to a frequency domain representation. The sum of the impulse noises can represent the impulse noise existing on the wide spectrum and can be converted from a frequency domain representation to a time domain representation using an inverse Fourier transform.

  • PASSWORD SCHEME THAT CAN BE USED FOR SECURITY OF MODEMS IN AN INDEPENDENTLY OPERATED CABLE SYSTEM THAT IS SCALABLE WITH DYNAMICALLY CHANGEABLE PASSWORDS
    Publication number: 20150244713
    Abstract: A password scheme is provided that can be used for security of cable modems in a cable network. In the system, the password is unique to each modem, the password is not fixed for the life of the device, is not shared across cable systems, is easily recoverable after a compromise, and is changed periodically based on some type of configuration. In the system each modem creates its own random password. Then the modem encrypts the password using a public key provided by the cable system and stores the encrypted password in a Management Information Base (MIB) operated by the cable system. The MIB operator decrypts the encrypted password corresponding to the public key and recovers the password. The cable operator uses the password to log in remotely to the modem. If a compromise or change of the public key or password occurs, the password is regenerated using the same procedure.

  • Method for fast reinstallation of deployed devices
    Patent number: 9094123
    Abstract: After a user device unsuccessfully attempts to establish upstream communication with a central network equipment downstream frequency to which it has tuned, an identifier corresponding to the tuned-to downstream frequency is removed from a cache of the user device. The frequency identifier stored in the cache typically corresponds to a frequency to which the user device has previously successfully tuned. The frequency identifier is removed from the cache after a predetermined attempt period, which may be determined by the number of attempts to establish communication that are made after previous unsuccessful attempts.

  • Media stream distribution system
    Patent number: 9094149
    Abstract: An arrangement is provided for transporting information from a central information distribution center (CIDC) to locations where such information is intended. Upon receiving a request for narrowcast information to be delivered to a node associated with a head end, the CIDC selects the requested information, generates an optical signal encoded with the requested information using information channels dedicated to narrowcast information transport for the node, and sends the optical signal to the head end via an optical fiber. When the head end receives the optical signal, the narrowcast information transport channels dedicated to the node are translated into subcarriers acceptable to the node before the requested narrowcast information is forwarded to the node.

  • OBI detection and avoidance in broadband devices
    Patent number: 9088358
    Abstract: Systems and methods can operate to detect and avoid optical beat interference (OBI) in broadband devices by use of restrictive channel assignment. An OBI-mitigating mapper algorithm can leash OBI candidates in a circular queue to avoid scheduling service flows likely to result in OBI generation. In some implementations, the algorithm can automatically leash all pre-DOCSIS 3.0 service flows. In alternative implementations, the algorithm can allow the CMTS to normally load balance pre-DOCSIS 3.0 devices while manually adding and/or removing pre-DOCSIS 3.0 service flows from the OBI candidate queue based upon lost transmissions or a designated age-out timer.

  • Re-synchronization of timing between communication devices
    Patent number: 9088390
    Abstract: Systems and methods of this disclosure can operate to re-synchronize timing between communication devices and can include a timing server. The timing server can provide timing messages containing timing correction values to communication devices that can synchronize the communication devices. If communication devices fail to receive timing messages, the communication devices may continue to provide communication services using their internal clocks that can drift over time. When timing messages are restored, the timing correction values can be significant enough to result in the loss of communications if immediately applied by communication devices. By gradually applying timing corrections over a period of time approaching the received timing correction value, communication devices can achieve re-synchronization while avoiding and/or minimizing the loss of communications.

  • Scheduler for High-Throughput System having Multiple Profiles
    Publication number: 20150188668
    Abstract: With the introduction of orthogonal frequency division multiplexing (OFDM) technology to communication channels in a cable network, cable modems that receive data downstream over subcarriers of the OFDM channel are grouped into modulation tiers based on at least one metric. Modulation tiers are generated at a subcarrier group level such that network elements can use different profile tiers depending in the subcarrier group in use. A scheduler facilitates the scheduling of modulation tiers for network element destination groups across subcarrier groups, where the modulation tier for a network element may vary between subcarrier groups. The scheduler also facilitates scheduling multiple network element destination groups for transmission of a plurality of subcarrier groups for optimal transmission to the network elements.

  • Determining Bitloading Profiles based on SNR Measurements
    Publication number: 20150188653
    Abstract: With the introduction of orthogonal frequency division multiplexing (OFDM) technology in to communication channels in a cable network, cable modems that receive data downstream over subcarriers of the OFDM channel are grouped in to modulation tiers based on at least one metric. A profile is generated for each OFDM channel based on the measurements across cable modems and subcarriers related to the OFDM channel, including the metric values used to group the cable modems in to the modulation tiers. Included in an OFDM profile may be a scheme for allocating marginal cable modems in to the plurality of modulation tiers. The methods and systems for generating modulation and coding scheme profiles enable more efficient modulation by network elements.
